Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. In a case in which the broadband is a 320 MHz band, the first phase rotation value is [1 1 1 −j j j j 1 j j j 1 −1 −1 −1 j].

Abstract: One embodiment of the present specification relates to a method for performing low-latency communications. According to one embodiment, an interframe space (IFS) for low-latency data may be suggested. The interframe space for low-latency data may be set to be greater than PIFS and smaller than DIFS. On the basis of the interframe space for low-latency data, a reception STA may perform EDCA and transmit low-latency data to a transmission STA.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information related to low latency traffic. The low latency traffic may be traffic requiring a latency less than or equal to a threshold value. A resource for the low latency traffic may be allocated to the STA. The STA may transmit, via the resource, a second PPDU including the low latency traffic.

Abstract: Proposed are a method and apparatus for receiving a PPDU on which BCC interleaving has been performed in a Multi-RU in a wireless LAN system. Specifically, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a Multi-RU which is an aggregate of a first RU and a second RU. The data field is generated on the basis of a coded bit string included in a BCC interleaver block. The coded bit string is obtained by interleaving a data bit string on the basis of first and second parameters. The data bit string is interleaved as the data bit string is entered into the BCC interleaver block in rows on the basis of the first parameter and is read out in columns of the BCC interleaver block on the basis of the second parameter.

Abstract: One embodiment according to the present specification relates to a method for constructing a preamble in a wireless LAN (WLAN) system. According to various embodiments, a PPDU may comprise a first signal field and a second signal field. The first signal field may include first information about PHY version. The first information may be determined on the basis of whether the PPDU is an EHT PPDU. The second signal field may include second information about the transmission of the PPDU, which is set on the basis of the first information.

Abstract: An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.

Abstract: Proposed is a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives an EHT PPDU from a transmission STA via a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information on a tone plan. The information on the tone plan includes allocation information indicating that a tone plan for the 320 MHz band is configured by four iterations of a tone plan for an 80 MHz band, which is defined in an 802.11ax wireless LAN system. The data field is received via an RU configured based on the allocation information.

Abstract: Proposed are a method and apparatus for performing sensing in a wireless LAN system. In detail, a first STA broadcasts a sensing request frame. The first STA receives a first sensing response frame form a second STA and receives a second sensing response frame from a third STA. The sensing request frame includes STA identifier information and RU allocation information. The STA identifier information includes identifiers of the second and third STAs. The RU allocation information includes information about a first RU allocated to the second STA and information about a second RU allocated to the third STA. The first sensing response frame is received through the first RU. The second sensing response frame is received through the second RU.

Abstract: An example according to the present specification relates to a technique for configuring a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may comprise an L-SIG field, an RL-SIG field, a first control field, and a second control field. A result of “modulo 3 operation” for a length field value of the L-SIG field may be set to “0.” The RL-SIG field may be configured to be the same as the L-SIG field. The first control field may comprise 3-bit information on the version of a PPDU, 6-bit information on a BSS color, and 7-bit information on TXOP.
